Dynamic Engineering Studies (Dynsim) Column Relief Load Reduction
Process Systems
Problem – Conventional methods are very conservative leading to overly expensive flare systems and unnecessary flare or flare header replacements.
Solution – Dynamic simulation provides an alternative to conventional calculation methods and provides substantially lower relief loads. Flare load reductions up to 50% are possible. – Dynamic simulation is consistent with API RP-521 methods.
Benefits – Save relief and flare system capital expenditures up to several million U.S. dollars.
Company Confidential
15
Dynamic Engineering Studies (Dynsim) Compressor Surge
Process Systems
Problem – Expensive compressors can be damaged by inadequate anti-surge control and equipment design.
Solution – Validate controls to keep compressors out of surge, especially during startup and shutdown. – Evaluate performance using hot gas bypass vs. cold gas bypass designs.
Benefits – Prevent damage multi-million dollar machinery.
Company Confidential
16
Dynamic Engineering Studies (Dynsim) Cryogenic Depressuring
Process Systems
Problem
– Vessels with light hydrocarbons become very cold during depressuring requiring expensive metallurgy.
Solution
– Calculate the mean metal temperature as a function of time during depressurization for gas processing and LNG applications. – The mean metal temperature is substantially less severe than the fluid temperature and expensive metallurgy and design choices can be avoided.
Comments
– Depressuring model is validated with actual data.
Benefits
– Avoid use of stainless steel metallurgy for savings up to several million U.S. dollars. Company Confidential

Improve Plant Performance Test Bed Value Proposition
Process Systems
By understanding an existing process better, small changes in the arrangement of existing plant equipment, feed point locations, operating conditions or control strategies can result in tremendous improvements in safety, yield, process variability, energy utilization, product quality & waste minimization. By understanding the existing controls better, small changes to control interlock logic and permissives, operator display organization, and controller tuning can result in tremendous improvements to emergency condition response and startup and shutdown procedures. We have a uniquely competitive position w.r.t. Foxboro I/A Series control systems.

Why do Dynamic Engineering?
Process Systems
Reduce Equipment Costs – Many design parameters are based on transient operating conditions.
Evaluate First of a Kind Plant Designs – These plants may have unforeseen process, control, and relief problems. – Reveal problems during design to avoid costly modifications after startup.
Validate Control Strategy – Test the control strategy as defined on a PFD. – Avoid costly troubleshooting and tuning efforts in the field.
Test Heat Integration – Complex designs with tight heat integration may need supplemental startup heat.
Analyze Flare and Relief Systems – Validate relief system design as a result of a Hazop analysis. Company Confidential
